1Can trees talk Yes but not in words Scientists have reason to believe that trees do communicate (交际) with each otherNot long ago researchers learned some surprising things First a willow tree attacked in the woods by caterpillars (毛虫) changed the chemistry of its leaves and made them taste so terrible
that they got tired of the leaves and stopped eating them Then even more astonishing the tree sent out a special smell—a signal (信号) causing its neighbors to change the chemistry of their own leaves and make them less tasty
Communication of course doesn’t need to be in words We can talk to each other by smiling raising our shoulders and moving our hands We know that birds and animals use a whole vocabulary of songs sounds and movements Bees dance their signals flying in certain patterns that tell other bees where to find nectar (花蜜) for honey So why shouldn’t trees have ways of sending message

(题包含5题题4分计20分阅读短文判断句子正误正确选T错误选F)
1By 2050 the world’s population is projected to rise to 9 billion from just over 7 billion currently Proponents of genetically modified foods say they are safe
and can boost harvests even in bad conditions by protecting against pests weeds and drought This they argue will be essential to meeting the needs of a booming population in decades to come and avoiding starvation
However Doug GurianSherman senior scientist for the food and environment program at the Union of Concerned Scientists an advocacy group said genetic engineering for insect resistance has provided only a modest increase in yields since the 1990s and droughtresistant strains have only modestly reduced losses from drought
Moreover he said conventional crossbreeding or crosspollinating of different varieties for desirable traits along with improved farming is getting better results boosting yields at a lower cost In fact much of the food Americans eat has been genetically modified by those conventional methods over thousands of years before genetic engineering came into practice
Overall genetic engineering does not get nearly the bang for the buck as conventional breeding and improve agricultural practices GurianSherman said His organization advises caution on GM foods and favors labeling though it acknowledges the risks of genetic engineering have sometimes been exaggerated
Andrea Roberto Sonnino chief of research at the UN food agency said total food production at present is enough to feed the entire global population The problem is uneven distribution leaving 870 million suffering from hunger He said world food production will need to increase by 60 percent to meet the demands of 9 billion by 2050 This must be achieved by increasing yields he added because there is little room to expand cultivated land used for agriculture
Genetically modified foods in some instances can help if the individual product has been assessed as safe he said It’s an opportunity that we cannot just miss

第五题写作(问答题)1题计20分
1请根列提纲写篇题绿色食品普作文少100词(Please write an essay of no less than100 wordsentitled Popularity of Green Food according to the outline given below)
(1)绿色食品现越越受消费者青睐
(2)什绿色食品受欢迎
(3)绿色食品更发展空间
标准答案
Due to its highquality and original tastes green food appeals to more consumers
From supermarkets to chain storesgreen food is found everywhere
Why is green food so popular even though its price is usually higher than other food One the one handrecently a series of issues on food safety makes customers disturbed and anxiousIn order to have the reliable foodmore housewives opt to select green food for their familyGreen food has been labeled as a kind of healthydelicious and fashionable foodThis is perhaps the most important reason for the popularity of green foodOn the other handwith the advance in living standardpeople will pay more attention to the quality of food and their raised income is enough to cover the expenditure of food with a comparatively high price
标准答案二
Green foods are becoming increasingly popular among consumers for several reasonsFirstlypeople are becoming more healthconscious and concerned about the quality of the food they eatGreen foodswhich are produced using natural and sustainable farming practicesare perceived as healthier and safer for consumptionThey are free from chemicalspesticidesand other harmful additives that can be found in conventional food
Secondlythe popularity of green foods can be attributed to the growing awareness of environmental issuesGreen foods are produced using ecofriendly methods that minimize their ecological impact and preserve natural resourcesConsumers are willing to pay more for green foods because they understand the environmental and social benefits of supporting sustainable farming practices
Finallygreen foods are expected to have even greater development in the futureAs more and more people become aware of the harmful effects of conventional farming practices on the environment and human healththe demand for green foods will continue to riseThis will encourage more farmers to switch to sustainable farming practiceswhich will bring more green food options to consumers
